LOUIS A. imam, or wnsrrmn, nassaomrsnr'rs FUEL BURNING APPARATUS Original No. 1,348,954, dated February 9, 1932. Serial No. 424,823, filed January 81, 1980. Application for reissue filed October 12, 1932. Serial No. 637,517.

This invention relates to improvements in fuel burning apparatus and is directed to apparatus for burning fuel oil and the like.

The novel features of the invention are concerned with apparatus which is especially adapted for use in connection with stoves and ranges whereby fuel oil may be used in place of coal.

The principal objects of the invention are directed to the novel combination and arrangement of parts hereafter more fully described in connection with the accompanying drawing, in which:

Fig. 1 is a side elevational view, partly in section, of an. apparatus embodying the novel features of the invention; 7

Fig.2 is a plan view of the apparatus shown in Fig. 1 with the cover removed; and

Fig. 3 is a small scale cover for the burner.

Referring to the drawing in detail the invention will now be described. A base 2-is provided which has a plurality plan view of the f upwardly extending and. concentrically in the form of a Y has the outer ends of its arranged, annular, spaced, rims or walls 4, 6, 8, 10and 12. V v

A central support or connecting member 22 upper arms 16 integral with the inner rim 4, leaving air supply passages through the base within the inner rim. Annular or channels 5, 7 and 11 are formed by-the' upwardly extending rims as shown. Passagewavs 18 in arms 16 are in communication with a central passageway 20 of the lower arm 22 of the support so that fuel may be delivered upwardly through the support and into the bottom of the depression 5.

A cover 24 h'aving'a central opening as shown rests upon suitable shoulders 23 in adjacent faces of the rims 4 and 6 so as to overlie the depression 5, forming a closed compartment adapted to serve as a vaporizing chamber. The lower side of the base is cut away between the rims 8 and 10 to pro-,

vide an annular air space or passageway 19 upwardly through the base and the rims 8;

at intervals by radial and 10 are connected lugs 25, see 2.

depressions The base member accordingly comprises an inner, radially broad, annular,'ba se por- 'tion provided with inner, outer and intermediate walls 4, 8 and 6, respectively, forming the channels 5 and 7 and a surrounding, rela tively narrow, annular, base portion spaced therefrom but connected by the lugs 25 provided with the walls 10 and 12, forming the channel 11.,

The rim-6 is cut away at intervals, as indicated by 26, to form ducts connecting the vaporizing compartment 5 with the channel 7, and openings 28 forming other ducts extend through the lugs 25 connecting the channels 7 andll so that fuel 'may find its way "into channel 11 from channel 5. Wicks 27v some material capable of absorbing oilchannels 7 and'11 as.

walls forming the wick-receivingc annels is" such that liquid fuel admitted to the vaporizng compartment may pass to the surroundlng wick-receiving channels and maintain a -bod'y of liquid fuel therein during the starting of the burner at a level well below the tops of said walls. I;

- A plurality of cylindrical .or tubular members comprising combustion tubes 30, 32, 34 and 36 are provided and are arranged in spaced, concentric relation. Their lower ends rest upon suitable shoulders at the sides of the rims and their lower sides face about the rims all as shown. In this way they are supported and held against relative shiftin movements. These cylinders are perforated as isindicated in Fig. 1 and may be made of any relatively thin metal.

There is thus provided an inner combustion chamber between the tubes 30 and 32 above and opening into the channel 7 and anouter combustion chamber between the tubes 34 and 36 above and opening into the channel ebaseandan passagesinthebase.

sligplied with air 1 the inner tube 30 supplied with air through the central air 7 space 43 therebetween.

inner combustion arranged annular rims including an inner- A cover 38 is provided which has a central late 40 and an annular ring 42 spaced thererom by arms 44. so as to form an annular .The cover rests upon the upper ends of the tubes so that the central tube is closed while the space-43 is dis-' posed above the depression 7.

In operation the apparatus is placed in the fire box of a range or stove and the support is connected by a suitable pipe to a supply of fuel oil. A suitable control valve is of course inserted in the pipe which when opened will allow fuel to How upwardly into the channel 5 from whence it will flow through cutouts 26 and passageways 28-into channels 7 and 11 and saturate the wicks 27.

The wicks are ignited from a flame inserted downwardly into the apparatus. As the base, cylinders and'other parts of the appara tus'become heated by the flames from the wicks the fuel'is vaporized as is desirable for combustion.

It will be noted that air may enter the apparatus upwardly through the annular slot 19 and through the central opening around the support 14 which is of course desirable forcombustion. The cylinders or tubes are easily removable to facilitate access to the wicks, etc. The apparatus is simple in construction so as to be economical to manufacture, while at the same time it is efiicient in its operation. a

The vaporizing chamber formed in the channel 7 beneath the cover plate 24 and underlying the inner air chamber provides a highly efiicient vaporizing chamber, particularly advantageous during the starting operation of the home During starting the vaporizing chamber has transmitted to the liquid fuel therein the heating'efiect of the quickly and intensely heated walls of the tube 30, not only through the intervening cover plate by way of both radiation and conduction, but also directly by conduction from the said tube through the intermediate wall 6, the latter forming one side of the vaporizing chamber and in turn also receiving further heat from the immediately adjacent wick.

While I have shown a single burner, it will .be obvious that a plurality of burners may be grouped together if desired. 7

Various changes may be made in the form of'the invention without departing from the spirit and scope-thereon Therefore I wish to claim and secure by Letters Patent of the United States the following: o 1.
